The center of the
D*AP8
Dolby processing is the
Metadata Processor
. It can be the point of origin of
metadata but it may also modify existing metadata from available sources:
The metadata processor of the
D*AP8
has a
maximum of seven metadata destinations
and four sources which can be routed
individually.
The
Metadata Generator
in the middle can
run independently but may take metadata
from an available source at the
"Input"
,
may select some or all of it in the
"
Follow Input"
section and present a
complete set of metadata at the "
Output"
.
Metadata Source Status - colors
The respective soft LED turns
red
if
no
metadata is present or the metadata are
corrupted.
It turns
green
if a
RDD 6
compliant
metadata stream is detected.
It turns
yellow
if an AC3 or similar (D-D+)
signal is decoded.
Metadata Source Status
[OK / Consumer / Fail / Not Available]
The word "
CONSUMER"
will be displayed to
indicate that only a metadata subset is
provided.
Metadata Destination
[OFF / D.Sub In / SDIx - VANC (if present) / DECODER (if present)]
The destinations can have any of the system sources assigned except
of the emulation engine [MD Emulation].

Generator Setup
The metadata processor generates
SMPTE
RDD 6
standard compliant metadata. It supports the most
relevant program configurations for broadcast applications (5.1 / 5.1+2 / 3x2 / 4x2) used with Dolby E 16
or 20Bit bit depth. Since the number of programs from an external RDD 6 stream may differ from the
generator setup, "off-size" program configurations will be handled this way:
If the input program configuration has more programs (e.g. 4x2) than the generator setup (e.g. 5.1+2)
and you click on a "surplus" program (Program 3 or Program 4), only an Input table will be displayed
while for the other programs an input and an output table is shown.
If the input program configuration has less programs (e.g. 3x2) than the generator setup (e.g. 4 x 2)
and you click on a "surplus" program (e.g. Program 4), an empty input table will be shown.
If the metadata generator is set up for "Follow Input" and the input program configuration does not
match the possible ones of the metadata generator it enters the reversion mode.
The output from the
metadata generator
is the source for the
emulator engine
but may also be
selected for optional built-in encoders and for metadata transport interfaces like
9-pin
(RS485) or
VANC
(SMPTE 2020).
